CFlowchartEditor is an extension of CDiagramEditor. CDiagramEditor is a vector editor, with a CWnd-derived window (CDiagramEditor), a data container (CDiagramEntityContainer) holding the draw-objects, undo stack and managing copy and paste, and objects derived from CDiagramEntity representing objects drawn on screen. CDiagramEditor lacks one feature (that is difficult to implement in both simple and general fashion) - links. Manually maintaining links in a - for example - flowchart or network topography map is unwieldy. Therefore, I ve created a reference implementation for one way of adding this functionality.
The ability to write efficient, high-speed arithmetic routines ultimately depends
upon your knowledge of the elements of arithmetic as they exist on a computer. That
conclusion and this book are the result of a long and frustrating search for
information on writing arithmetic routines for real-time embedded systems.
With instruction cycle times coming down and clock rates going up, it would
seem that speed is not a problem in writing fast routines. In addition, math
coprocessors are becoming more popular and less expensive than ever before and are
readily available. These factors make arithmetic easier and faster to use and
implement. However, for many of you the systems that you are working on do not
include the latest chips or the faster processors. Some of the most widely used
microcontrollers used today are not Digital Signal Processors (DSP), but simple
eight-bit controllers such as the Intel 8051 or 8048 microprocessors.
AI::Categorizer is a framework for automatic text categorization. It consists of a collection of Perl modules that implement common categorization tasks, and a set of defined relationships among those modules
In a preemptive priority based RTOS, priority inversion
problem is among the major sources of deadline
violations. Priority inheritance protocol is one of the
approaches to reduce priority inversion. Unfortunately,
RTOS like uC/OS can’t support priority inheritance
protocol since it does not allow kernel to have multiple
tasks at the same priority. Although it has different ways
to avoid priority inversion such as priority ceiling
protocol, developers still have some difficulties in
programming real time applications with it. In this paper,
we redesign the uC/OS kernel to provide the ability to
support round robin scheduling and implement priority
inheritance semaphore on the modified kernel. As result,
we port new kernel with priority inheritance semaphore to
evaluation board, and evaluate the execution time of each
of the kernel service as well as verify the operations of
our implementation.
DAGON Approach
Object of this exercise:
Given a subject graph and a set of pattern graph in canonical representation (2-input
NAND and INV), implement the second step of DAGON approach. (Both the subject
graph and the pattern graphs are trees.)
An unsatisfactory property of particle filters is that they
may become inefficient when the observation noise is low.
In this paper we consider a simple-to-implement particle filter,
called ‘LIS-based particle filter’, whose aim is to overcome
the above mentioned weakness. LIS-based particle
filters sample the particles in a two-stage process that uses
information of the most recent observation, too. Experiments
with the standard bearings-only tracking problem indicate
that the proposed new particle filter method is indeed
a viable alternative to other methods.
radius協議源碼÷The Radius Stack will connect to a Radius Server. This stack
implementation is built upon the UdpStack which is available
in the radius{version}/util directory. A minimal set of VSAs (Vendor
Specific Attributes are supported by this stack). The Radius
Stack should be used as a base class. In order to implement
a larger set of VSAs, one will need to subclass from the
Radius Stack and implement the functionality within the
virtual function processVsa(). The Radius Stack supports
mostly accounting messages. The authentcation messages
will be supported in a future release.
A test program has been provided in the radius directory.
This program shows how to subclass from the RadiusStack
and how to use the api.
There is a shared object – int array[] between Write and Read. Write sets the array, Read gets the array and sorts ascending. Write a program to implement the write/read question by using synchronization mechanism and GUI.
The program md.f implements a simple molecular dynamics simulation in continuous real space. The velocity Verlet algorithm is used to implement the time stepping. The force and energy computations are performed in parallel, as is the time integration. (The program uses some Fortran90 features, so an F90 compiler may be needed.)
